Abstract: PURPOSE: A system and method for verifying a certificate are provided to minimize a certificate verification procedure using only a public key of a Root CA(root certification authority) without the acquisition of public key information of a local authentication server. CONSTITUTION: A first local authentication server(200) requests a corresponding signature value of a first initial parameter to a Root CA(100)(S501). The Root CA transmits the signature value of the first initial parameter to corresponding to the request of the first local authentication server to the first local certificate server(S502) The first local authentication server issues a certificate about a first terminal(300) and one or more terminals. The first terminal requests its own certificate to the first local authentication server(S503). The first local authentication server transmits the certificate corresponding to the first terminal to the first terminal(S504). The first terminal requests the certificate reissuance to the first local authentication server(S505). The first local authentication server transmits the reissued certificate to the first terminal(S506). [Reference numerals] (100) Root CA; (200) First local authentication server; (300) First terminal; (AA) Detection of an expiration date of a certificate; (S501) Request of a first initial parameter signature value; (S502) Issuing the first initial parameter signature value; (S503) Request of the certificate; (S504) Generation of the certificate; (S505) Request of the certificate for reissuing; (S506) Issuing the certificate for reissuing
